Activities

The EventBus is bound to the global scope as Singleton. If we move to single root system. This should also be changed to the normal way.
Also we should remove all render functions in vue js. the whole topbar component has to be rewritten for this.
We are using different building systems. Move to one solution and use it everywhere.
Multiple Vuex implementations. => Move to one Vuex store.

@ollehar: Another important detail to consider is the way VueJS can play together with plugins. At LS 3 we had various ways for a plugin to add a new button or menu entry to the admin interface. With vueJS to me it loos like we made several steps backwards regarding integration of plugins.
